IRU1117-18PBF

Data Sheet No. PD94137 revA IRU1117-18(PbF) FEATURES Guaranteed < 1.2V Dropout at 800mA Load Current Fast Transient Response 1% Voltage Reference Initial Accuracy Built-In Thermal Shutdown Available in SOT-223, D-Pak, Ultra Thin-PakTM and 8-Pin SOIC Surface-Mount Packages APPLICATIONS Low Voltage IC Supply Applications PC Clock Supply Voltage 800mA LOW DROPOUT POSITIVE FIXED 1.8V REGULATOR DESCRIPTION The IRU1117-18 is a low dropout three-terminal fixed output regulator with minimum of 800mA output current capability. This product is specifically designed to provide well regulated supply for low voltage IC applications as well as generating clock supply for PC applications. The IRU1117-18 is guaranteed to have <1.2V dropout at full load current making it ideal to provide well regulated with 3.8V input supply. The IRU1117-18 is specifically designed to be stable with low cost aluminum capacitors while maintaining stability with low ESR tantalum caps.
